Bolandiol (INN), also known as 19-nor-4-androstenediol, estr-4-en-3β,17β-diol, or 3β-dihydronandrolone, is an anabolic-androgenic steroid (AAS) that was never marketed. A dipropionate ester, bolandiol dipropionate (brand names Anabiol, Storinal; former developmental code name SC-7525), has been marketed. Bolandiol (and its dipropionate ester) is unique among AAS in that it reportedly also possesses estrogenic and progestogenic activity.
Bolandiol is on the World Anti-Doping Agency's list of prohibited substances, and is therefore banned from use in most major sports. It is a potential metabolic precursor to nandrolone. However, several clinical studies have concluded that bolandiol does not alter strength, body composition, or exercise performance.
